Once I called Jumbo,believing my septic needed them. But Mr. Nani from Jumbo explained to me that the problem I had, needed other workers . He showed me where the problem was, explained the solutions and he did not wanted to be payed for "an advice only". I am totaly convinced of the seriosity of JUMBO and many of my friends as well. Don`t look for alternatives, when you can have a good service. Maybe you find cheaper service, but don`t cry if you find out, that the cheap was cheat.
